Created frontend provisioning script

This script handles pulling in all of the frontend's dependencies. It also creates a symlink from the node_modules directory inside the shared /vagrant folder to the Vagrant VM's home folder. This fixes issues in windows where npm install tries to create symlinks in a NTFS backed file system. It also speeds up the npm install process as Virtual Box's shared folder engine is significantly slower than a native file system, especially with npm's large number of small files.
